Toymaker, also known as the Celestial Toymaker, was a powerful being who ensnared sentient beings in seemingly childish games, with their freedom as the stakes. However, the Toymaker hated to lose and the games were always rigged in his favour. There were many contradictory accounts of the Toymaker's identity; one equated him with the Chinese trickster-god No Cha, (PROSE: Christmas on a Rational Planet [+]) and others claimed that he was one of the Guardians of Time, either the Crystal Guardian, (PROSE: The Quantum Archangel [+]) or the Guardian of Dreams. (PROSE: Divided Loyalties [+]Gary Russell, BBC Past Doctor Adventures (BBC Books, 1999).)
